Recording of a webinar broadcast on July 15, 2020. RADAR has been designing ADUs since the very earliest days of the firm. In the beginning these were rec rooms or home offices which sometimes pushed the limits of legality. In the interim, policy changes have caught up with individual and societal pressures and now ADUs are encouraged by the same jurisdictions which used to police or forbid them. In this presentation RADAR Principal Rachel Allen presented the history of this project type by the office, shared many of the innovative design ideas which we developed over the years, and fielded questions.
